Scientists in Argentina are studying the effect of methane produced by livestock on global warming. To measure the amount of gas produced by cows, animals have been outfitted with pink tanks to collect their farts!

The Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country's total greenhouse emissions.

As one of the world's biggest beef producers, Argentina has more than 55 million cows grazing in its famed Pampas grasslands.

Guillermo Berra, a researcher at the National Institute of Agricultural Technology, said every cow produces between 8000 to 1,000 litres of emissions every day.

Research like this is a total waste of money??? They will learn the feasibility and cost of capturing cow farts and the amounts of methane released. Sounds like if X < Y they profit and reduce emissions.
